# AI workflow delivery cost calculator — WorkflowCost

Canonical: https://agiscorecard.com/workbench/workflowcost
Language: en
Method version: 2026-09-19.2

Model retries, human review and fixed costs before quoting an automated workflow.

## How this tool works

Expected attempts = 1 + p + … + p^retries. Completion probability = 1 − p^(retries+1). Monthly cost includes execution attempts, review labor and fixed costs.

## Input format

- Submitted runs per month: `runs`
- Input tokens per attempt: `input`
- Output tokens per attempt: `output`
- Price per million input tokens: `inputrate`
- Price per million output tokens: `outputrate`
- Other execution cost per attempt: `other`
- Failure probability per attempt (0–0.99): `failure`
- Maximum retries: `retries`
- Human review minutes per submitted run: `minutes`
- Human review cost per hour: `hourly`
- Fixed monthly cost: `fixed`

      "250.00"
    ],
    [
      "Fixed monthly cost",
      "20.00"
    ],
    [
      "Monthly total",
      "293.98"
    ],
    [
      "Cost per expected completed run",
      "0.29"
    ]
  ]
}
```

## Limits and assumptions

All money inputs must use the same currency. Failure probability is assumed constant and independent per attempt; correlated outages violate that assumption.

Human review minutes apply once per submitted run. Provider prices are your inputs, not a maintained price feed.
